APPLICATION OF CANADIAN VYTELLE GROWSAFE TECHNOLOGY FOR DETERMINING RESIDUAL FEED INTAKE IN RAISING QAZAQ AQBAS BULL CALVES

Abstract

The article describes using GrowSafe technology that is widely used in countries with a developed agro-industrial complex, with the aim of introducing it in Kazakhstan to assess the breeding and beef qualities of the Qazaq Aqbas cattle. At this time, GrowSafe technology is being implemented in Zhana Bereke LLP, Akmola region. Data from GrowSafe database was used for research. According to the data obtained, the expected residual feed intake from progeny (RFI EPD), the average daily gain of the expected progeny difference (ADG EPD), the expected progeny difference in dry matter intake (DMI EPD), residual feed intake (RFI), residual average daily gain (RADG), average daily live weight gain (ADG), dry matter intake, average per day of animals during the trial (DMI). According to the research results, the average value of RFI EPD for group 1 is -0.0607, for group 2 is -0.0297. ADG EPD is higher in group 1 (-0.0018) compared to group 2 (-0.0005). The DMI EPD index is equal for the first group -0,0600, for the second group -0,0292. Residual feed intake for group 1 varied from -0.81 to 1.11, for group 2 - from -0.80 to 1.09. The RADG indicator for group 1 was at the level from -0.57 to 0.58, for group 2 from -0.58 to 1.13. The average live weight at the beginning and end of the Trial in the first group was 254.16 and 287.62 kg, in the second group 239.99 and 273.09 kg. The ADG forboth groups was at the same level 0.70 and 0.69. The DMI is higher in the first group - 4.15. In the second group, this indicator was 3.65.
